You should call DAN and talk to someone who might actually have an answer.
A few years ago, Mrs. Stoo severely broke her leg skiing. (Spiral fractures, six of them, in both her tib and fib, requiring a rod and six screws to be put back together.)
After a very slow recovery, we planned a trip almost two years after the fracture. I called DAN as her leg continued to cause her some discomfort. As I recall, the answer I got was something like "Wait a year after a complete recovery". When it appeared she was unlikely to ever have a "complete" recovery, I called again, and got a less specific answer. I came to the conclusion that there was no "correct" answer..
I finally sent an email to a friend who happens to be a well knows diving physician. His response was basically, "Take it easy, and if it hurts after diving, suck some O2 and don't do it again"! (Needless to say, I'm not going to mention his name!)
So that's what we did... and she suffered no ill effects at all. We kept our profiles to ND times and so on of course.
Your finger is a very minor break by comparison, BUT it isn't healed yet. I suspect that you will could ask ten diving doctors and you'll get different 10 answers.
My guess (and it is only that), is that as long as you take it easy and don't push your times, you will be absolutely fine. The worst thing that could happen is you might get a wee bend in your finger, but it's not likely to be fatal!
